Exploration Update

Highlights

• First phase of exploration completed at Mt Cattlin lithium project in Western Australia

• 1,077 auger holes drilled with 1,143 samples taken for analysis – results expected in June Quarter

• Heritage survey completed at the Labyrinth gold/REE project with drilling scheduled to commence in late April

• Three nickel-copper targets at Mt Venn to be drilled in the June Quarter

• Drill targets defined by EM surveys at Wyloo gold JV, with heritage survey pending prior to drilling

• Airborne EM survey to be completed at the Musgrave Project in June Quarter

Woomera Mining Limited ( ASX: WML ) (“ Woomera ”, “ the Company ”) is pleased to provide an update on exploration activities underway on its suite of projects in Western Australia and South Australia. With a sound cash position of c$2.5m, the Company is well placed to commence further exploration, with a proposed budget for its current drilling programs of c$350,000.

Mt Cattlin Lithium (100% - Western Australia)

At the Mt Cattlin lithium project near Ravensthorpe in WA, auger geochemistry has been completed over 60% of the prospective trend that runs through the Company’s tenement.

Auger samples were collected on a 200-metre by 50-metre pattern over farmland, with assay results expected in the June Quarter 2023.

The Company will plan further work on the farmland areas once results from the auger program have been assessed.

The remainder of the tenement is covered by remnant bushland and geochemical sampling will be undertaken on these areas once relevant approvals are secured.

Mt Venn Nickel-Copper (80% - Western Australia)

As part of Woomera’s tenement assessment program, it was determined that additional drilling is justified in what may be a “near miss” situation with EM anomaly EMJVA24 on Exploration Licence 38/3150, which was drilled in 2022.

The conductor has a relatively high conductance of about 9,000 siemens (S) and remodelling by external consultants NewExco has concluded that the target was not effectively tested by previous drilling. Drill hole MVRC064 intersected 2m @ 1.3% Cu from 42m and 2m @ 0.9% Ni from 47m and is considered to have drilled near the edge of the anomaly.

Drill testing of two high order EM conductors JRVA22 and JRVA25 (7,500-10,000 siemens) located to the northeast of EMJVRA24 on recently granted Exploration Licence 38/3581, will also be completed.

Labyrinth Gold-REE (100% - South Australia)

A heritage survey has been completed over the area prospective for gold and REE at the Labyrinth project and initial RC drilling is scheduled to commence in late April, with results expected at the end of the June Quarter 2023.

Wyloo Gold (60% - Western Australia)

The Company has completed its review of the airborne EM survey flown at the Wyloo JV in the Ashburton region of WA in the December Quarter 2022 and has identified two targets for drill testing in 2023. Heritage surveys have been requested for the New Morning and Golden Marra Mamba prospects and drilling will be planned once the surveys are completed.

Musgrave Nickel-Copper (100% - South Australia)

An airborne EM survey is scheduled to commence over the Company’s Musgrave Project in April 2023, with results expected in the June Quarter 2023.

This ASX announcement has been approved and authorised for release by the Board of Woomera Mining Ltd.
